Google's DeepMind Plans To Build Blockchain-Style System To Track Patient's Record

Google’s DeepMind, plans to build blockchain-style system that will cautiously track, when, where, how and by whom patient’s data is used for care and for research.

There is a plan to create a digital ledger that automatically captures every interaction made with patient’s data so if there is any change in the record will be viewable.

DeepMind has disclosed that it will develop a tool, will be known as ‘Verifiable Data Audit’ which will allow hospitals and patients both to track every piece of patient’s data. The new system will keep the record in cryptographic manner to ensure the accuracy of data. Every time when data will be used, a new code would be generated. It means that if someone tries to edit the record later on to hide the fact that data was used before for a specific purpose, will be revealed immediately.

DeepMind has already made an agreement with London’s Royal Free Hospital to test and conduct an experiment with the new tool in order to ensure impeccable working of tool. The hospital staff will be allowed to see how the patient’s data is used in real-time. And if any sort of unusual use is observed, an automated signal will indicate it.

Mustafa Suleyman, co-founder of DeepMind, said that developing ‘Verifiable Data Audit’ is an attempt to overcome all existing issues prevailing with patient’s data handling, which ensures incredibly clear and clean audit of data.

DeepMind is continuously taking one of the other initiatives and quickly developing lots of various health-care tools including AI system to diagnose eye disease and machine learning to guide cancer treatment. But it has put the company in a conflict, where a document collected by New Scientist reveals that a data sharing agreement made between DeepMind and UK’s National Health Service goes far beyond what was publicly acknowledged.

Suleyman made a statement that “Our mission is absolutely central, and a core part of that is figuring out how we can do a better job of building trust. Transparency and better control of data are what will build trust in the long term.” And further adding a number of efforts made to build that trust, starting from its foundation of a board of independent reviewers for DeepMind health to its membership of the industry group Partnership on AI.

But Perrin said that the approach DeepMind has adopted would surely let them win public trust and further added that the main reason for such criticism, made against the partnership of DeepMind and UK’s National Health Service was the inability of distinguishing between uses of data for care and for research. But DeepMind is on the right track to succeed over challenge.

DeepMind has extreme hopes for the proposal, expecting it to be used outside the healthcare too. At present, there is no such mechanism that patients can know about where their data has moved but with the advent of this new tool, people would be able to track their data.

It is said that this technology can be used for plenty of other companies. Maersk, the world’s largest shipping company is also testing it to keep track its cargo.
